The Lowdown
Alright folks, Rusty here. Let’s get into it.
The outlook for Jaconé isn’t looking like a classic right now, but there’s a little pulse of energy building towards the end of the week and into the weekend that’s got my attention. The water’s sitting at a warm 72°, which is pretty much bang on average for this time of year, so no surprises there.
The real standout in this whole 16-day window is the Saturday morning session on the 1st of August. We’ve got a clean 3ft of swell rolling in from the south, with a solid 12-second period. That’s a proper groundswell, packing a moderate punch with a combined energy of 252. The real kicker is the wind: a light offshore from the NE at 3 mph. That’s going to groom the waves beautifully, making for a clean, glassy morning. The swell direction is a touch east of their optimum, but with that offshore wind and consistent swell, it’s your best bet. The crowd factor is a consideration here – it says “sometimes” busy, so you might have a few locals out, but it’s worth it.
The next morning, Sunday the 2nd of August, is a decent little follow-up. The swell drops a bit to 2ft from the south, but the wind is still light offshore from the NE at 3 mph. It’s a smaller, cleaner option for the early crew.
The week after that shows a bit more energy. Monday the 4th of August has a morning push of 5ft from the ENE, but with a short, weak period of only 7 seconds. That’s a lot of chop, not much shape. Then Wednesday the 5th of August morning has a nicer 3ft south swell with an 11-second period, and the wind is offshore again. That’s a solid, clean option.
Later in the second week, the morning of Thursday the 6th of August has a punchy 5ft from the ENE with a short period again, but the wind is offshore. It’s going to be a bit of a mess, but for the expert crew, there’ll be some power to push through. Friday the 7th of August morning has a 4ft ENE swell with a light offshore wind, and the afternoon goes glassy with a 2ft south swell. Those are small windows but clean.
There’s a bit of a gap after the 9th, with wind and swell directions not playing nice. The last few days of the forecast look a bit messy with onshore winds, so the window is pretty narrow.
So, to sum it up: your best bet is the Saturday morning of the 1st of August. Get out there early for the cleanest lines.
Rusty.

Information about the Jaconé Surf forecast
The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
